About
Didiplis diandra is a stem plant in the family Lythraceae, native to North America. It bears fine, needle-like leaves densely along the stem, and under ample lighting with CO2 injection the leaf tips color from orange to red, which is its main appeal. The green-to-red gradient is beautiful, and its delicate form creates an airy background to midground effect when grown in groups. Strong lighting, CO2, and iron-containing liquid fertilizer are important for both coloration and healthy growth; lower leaves drop easily when light or nutrients are lacking. Growth is relatively fast, and it can be propagated by trimming and replanting tops. Being delicate and sensitive to environmental change, it requires stable water management and is suited to advanced hobbyists. It prefers soft, slightly acidic to neutral water.
